[Bug 1775897] [NEW] "Update Software" not opening

[david braun]

Public bug reported:

The "Update Software" Icon showed that there were updates available
(small triangle on left edge). Left clicking on icon didn't appear to do
anything (no window appeared). Right clicking displayed a menu of
options. Based on a previous encounter with this problem I entered

  "wmctrl -R "Software Updater"

which opened the expected window in the center of the screen.

I expected a dialog listing the updates available.

Nothing happened.
